Publication number: 20240031696Abstract: A method for correcting image data includes receiving image data associated with an image captured by a photosensor array and determining a location of a target pixel in the photosensor array associated with a defect of the imager. First operating pixels are identified in a first region of the photosensor array that overlaps the location of the target pixel and second operating pixels are identified in a second region of the photosensor array that overlaps the location of the target pixel and a portion of the first region. A simulated pixel value is determined for the target pixel in response to a weighted average of the first operating pixels and the second operating pixels. The simulated pixel value is assigned to the target pixel in the image data.Type: ApplicationFiled: July 14, 2023Publication date: January 25, 2024Applicant: Gentex CorporationInventors: Andrew J. Oosterhouse, Dale M. Radcliff

Patent number: 11178353Abstract: A display system is provided for a vehicle equipped with a camera for supplying streamed video images of a scene rearward of the vehicle. The display system includes an image processing unit for receiving the streamed video images and processing the streamed video images, and a display for displaying the processed streamed video images. To perform processing of the streamed video images, the image processing unit is configured to: detect amplitude-modulated light sources in the streamed video images, classify the detected amplitude-modulated light sources into one of several possible classifications, select the streamed video images in which an amplitude-modulated light source is detected that flickers based upon the classification of the amplitude-modulated light source, and modify the selected streamed video images to correct for flicker of any amplitude-modulated light sources in the selected streamed video images.Type: GrantFiled: June 22, 2016Date of Patent: November 16, 2021Assignee: GENTEX CORPORATIONInventors: Tom B. Sherman, Daniel G. McMillan, Dale M. Radcliff, Igor Majdandzic, Gregory S. Bush

Publication number: 20090144025Abstract: A method is disclosed for determining the operating condition of a medical pump based on data derived from a pressure sensor and a position sensor. The pressure sensor generates pressure data by sensing the force on the pumping element. The position sensor generates position data by tracking the pumping cycle and determining the position of the pumping element. The pump pressure data and pump position data are processed and the calculated results compared with a pre-determined threshold value to determine the operating condition of the pump. The three main types of operating conditions of concern are the following: normal condition, where liquid is present and no leaks exist in pumping chamber; leak condition, where liquid is present but a leak exists in the pumping chamber; and air stroke condition, where the chamber contains some air.Type: ApplicationFiled: June 27, 2008Publication date: June 4, 2009Applicant: Abbott LaboratoriesInventors: Chad E. Bouton, Dale M. Radcliff, Steven R. Nelson, Clark E. Fortney

Publication number: 20090143727Abstract: A medical pump, for use with a cassette having a pumping chamber, includes a pumping element with a piston slider assembly which intermittently pressurizes the pumping chamber during a pumping cycle and has a piston head connected to a main body with a single pressure sensor positioned there between. A camshaft is associated with the pumping element, an inlet control element, and an outlet control element for closing the pumping chamber to flow when the pumping chamber is pressurized. A processing unit receives pressure and position data from the pressure sensor and a position sensor associated with the pumping element, and processes this data to determine the operating condition of the pump. The operating conditions determined include: blocked fluid flow, no fluid in the line, no cassette associated with the pump, proper pump priming, or proper valve sealing.Type: ApplicationFiled: July 11, 2008Publication date: June 4, 2009Applicant: Abbott LaboratoriesInventors: Chad E.
